The Gains Calculator is an online fitness planning tool that helps users:

  • Calculate weight gain needed to reach a target body weight
  • Estimate time required (weeks) to achieve fitness goals
  • Determine daily calorie target for muscle growth
  • Suggest weekly muscle gain rate based on calorie surplus
  • Recommend protein intake for muscle building
  • Classify training intensity level based on workout frequency

It combines nutrition science and fitness principles to create a simple roadmap for muscle gain and body transformation.
